See the Light—Without the Strain: Why Blue Light Glasses Are the New Must-Have by Holistic Nurse Practitioner Emily MacLeod Wolfe
In our modern world, screens dominate nearly every aspect of daily life—from computers and smartphones to tablets and televisions. While these devices keep us connected and informed, they also emit a high-energy wavelength known as blue light. Although essential during daylight hours for regulating our circadian rhythm, excess exposure to artificial blue light after sunset can disrupt our body's natural balance, impacting hormones such as cortisol and melatonin and ultimately affecting our overall well-being.
Understanding Blue Light and Its Impact on the Body
Blue light is a part of the visible light spectrum with short wavelengths and high energy. During daytime, exposure to blue light helps maintain alertness, cognitive function, and mood by regulating the secretion of cortisol—a hormone that helps us wake up and stay attentive.
However, artificial blue light exposure in the evening, especially from screens, tricks the brain into thinking it’s still daytime. This suppresses melatonin secretion, the hormone responsible for signaling the body to prepare for sleep. Reduced melatonin disrupts circadian rhythm, leading to poor sleep quality, difficulties falling asleep, and impaired immune function.
How Does Blue Light Affect Cortisol and Melatonin?
Cortisol Dysregulation: Typically, cortisol peaks in the early morning and gradually declines throughout the day. Excess blue light at night can cause cortisol levels to remain elevated later in the evening. This prolonged elevation may result in increased stress, anxiety, and difficulty relaxing.
Melatonin Suppression: Blue light exposure after sunset inhibits melatonin production, delaying the onset of sleepiness and reducing total sleep time. Because melatonin also supports antioxidant pathways, its suppression can increase oxidative stress and inflammation.
The Holistic Solution: Blue Light Glasses
Blue light glasses are eyewear equipped with lenses that filter or block a significant portion of blue light wavelengths, especially during evening hours. Integrating blue light glasses into your daily routine offers several benefits:
Protecting Circadian Health: By minimizing blue light exposure when the body expects darkness, these glasses help preserve natural melatonin rhythms, promoting restful and restorative sleep.
Reducing Eye Strain: Screens emit intense blue light that can cause digital eye strain symptoms such as dryness, headaches, and blurred vision. Wearing blue light glasses can alleviate these symptoms, improving comfort during prolonged screen use.
Supporting Hormonal Balance: By normalizing cortisol and melatonin secretion patterns, blue light glasses support the body’s natural stress response and recovery cycles.
Incorporating Blue Light Glasses Into Your Routine
To maximize benefits, wear blue light glasses 2-3 hours before bedtime, especially if you are using electronic devices during this time. For daytime use, glasses with a lighter tint can help reduce glare without compromising alertness.
In addition to blue light glasses, consider these holistic strategies to support healthy circadian rhythms:
Limit screen time in the evening.
Use “night mode” or blue light filter settings on devices.
Engage in calming activities like reading a book or gentle stretching.
Ensure exposure to natural daylight during the day to reinforce circadian cues.
